Physics and astrophysics of strong magnetic field systems with eXTP
Andrea Santangelo, Silvia Zane, Hua Feng +38
In this paper we present the science potential of the enhanced X-ray Timing and Polarimetry (eXTP) mission for studies of strongly magnetized objects. We will focus on the physics…
NuSTAR Hard X-ray View of Low-luminosity Active Galactic Nuclei: High-energy Cutoff and Truncated Thin Disk
George Younes, Andrew Ptak, Luis C. Ho +5
We report the analysis of simultaneous XMM-Newton+NuSTAR observations of two low-luminosity Active Galactic Nuclei (LLAGN), NGC 3998 and NGC 4579. We do not detect any significant…
Constraining the limiting brightness temperature and Doppler factors for the largest sample of radio bright blazars
I. Liodakis, T. Hovatta, D. Huppenkothen +3
Relativistic effects dominate the emission of blazar jets complicating our understanding of their intrinsic properties. Although many methods have been proposed to account for them…
The first tidal disruption flare in ZTF: from photometric selection to multi-wavelength characterization
Sjoert van Velzen, Suvi Gezari, S. Bradley Cenko +37
We present Zwicky Transient Facility (ZTF) observations of the tidal disruption flare AT2018zr/PS18kh reported by Holoien et al. and detected during ZTF commissioning. The ZTF ligh…
Detection of non-thermal X-ray emission in the lobes and jets of Cygnus A
M. N. de Vries, M. W. Wise, D. Huppenkothen +7
We present a spectral analysis of the lobes and X-ray jets of Cygnus A, using more than 2 Ms of observations. The X-ray jets are misaligned with the radio jets a…
Rotational phase dependence of magnetar bursts
C. Elenbaas, A. L. Watts, D. Huppenkothen
The trigger for the short bursts observed in -rays from many magnetar sources remains unknown. One particular open question in this context is the localization of burst emission…
